In 1999, the City of Daytona Beach, Florida, had one water treatment and two wastewater treatment facilities within its service area that exceeded the 2,500- pound threshold limit for gaseous chlorine. As a result, a Risk Management Plan(RMP) would have to be prepared and submitted to the Environmental Protection Agency Risk Management Planning-Accidental Release Prevention Program.

While developing their RMP, the City staff further evaluated the chlorination facilities at one particular location -- The Ralph Brennan Water Treatment Plant -- and determined that the 25-year old system was reaching the end of its usefullife and that approximately 40 hours were spent on site-specific RMP paperwork, maintenance and operational procedures every month. Therefore, the City decided to embark on a program to replace the gaseous chlorine system at the Brennan Plant with a treatment technology that would put them in better compliance with or eliminate RMP guidelines at that location.

The City staff conducted evaluations of three treatment alternatives: rehabilitation/replacement of the existing gaseous chlorine system, bulk purchase of commercially available sodium hypochlorite solution, and on-site generation of sodium hypochlorite. The City staff decided to place a greater emphasis on trying to eliminate the use of any hazardous disinfection chemical at the plant -- a decision that accelerated the evaluation of the last two treatment alternatives; bulk and on-site sodium hypochlorite

Readily available potable grade bulk sodium hypochlorite solution ranges between a 12-15% concentration, a solution strength that is still considered a hazardous material and is subject to containment requirements. Therefore, the 0.8% solution strength produced through the use of on-site generating systems was favored by the City. Before making the final decision to install an on-site generation treatment system at the Brennan Plant, however, the City operations and engineering staff visited facilities, including plants in Vero Beach, Fl., West Palm Beach, Fla. And City of Ocoee, Fla., that were using on-site generation systems. After discussing the operational and maintenance requirements of on-site generation systems and receiving feedback on the simplicity of the process and the reliability of the operation, the City of Daytona Beach chose on-site generation as its preferred disinfection process.

Many Tampa residents received a notice in the mail a few days ago alerting them that the city is temporarily changing their disinfecting agent from chloramines to chlorine. The notice, which you can read in full below, claims that this procedure is merely routine maintenance and that the water will still be safe to drink.
Citizens who aren’t familiar with water treatment methods may read the notice and immediately discard it during the rush of another busy day. But this announcement, coming on the heels...

Increasingly, more hydro projects are being integrated into existing conduit and canal systems such as potable water supply systems, waste water treatment plants and even on irrigation canals. Ossberger Hydro has a lot of experience in these types of projects with many features that have been designed specifically to address the characteristics of such projects. Shown below is an example of a project in a water supply system at Marron Creek and an article that goes into detail.

As cities and urban landscapes expand across the globe, water resource management continues to pose a huge challenge. Natural wetlands are often built over as cities grow, but a recent strategy of green infrastructure applies the opposite principle – wetlands are protected and constructed as part of city planning.
Wetlands, whether natural or man-made, act as large-scale storage and filtration centers for water streams. Beyond providing a habitat for wildlife and greenery in otherwise urban landscapes,...

Well Water Treatment Systems | Industrial & Commercial
Well water treatment systems are used to purify water and eliminate impurities from all types of well water (dug wells - driven wells - drilled wells).
To have the right and the most efficient well water treatment system, you need to correctly analyze the well water chemistry and to have a fundamental understanding of how the well water system works.
Most water treatment systems perform within certain conditions. Well water for example here is naturally...
